Mac
Find the AI model that fits your Mac, run it in one click and chat with it privately. Free, no account, nothing sent to an AI company.
Run AI on your own Mac, privately. AiTuner finds the most capable model your Mac can run, downloads it, starts it in one click and gives you a private chat with it. No Terminal, no Python, no account: Apple's MLX is built into the app.
GET STARTED IN ONE CLICK
Get started benchmarks your Mac, then downloads and runs the most capable MLX model for it. Choose AI Performance (the most capable model) or AI Memory (the longest context window); a ring shows how your Mac's memory splits between the model and its context.
WHICH MODEL FITS YOUR MAC
Models draws each MLX model against your Mac's unified memory at the context you choose (16K, 32K or 128K, with an fp16 or 8-bit KV cache): fits, tight or won't fit, with its size and a flag for its maker's country. Choose which countries' makers you see in Settings. Download and run locally in one click, or name any MLX model on Hugging Face.
LOCAL AI: YOUR PRIVATE CHAT
- Chat with the model AiTuner runs, or one loaded in Ollama or LM Studio on this Mac.
- Nothing of the chat is kept or sent anywhere.
- A thinking model's reasoning is shown apart from its answer.
- GPU, CPU, memory and speed live beside the chat; the full monitor is one click away.
- Long conversations are compressed for you at 70% of the context window (change it in Settings).
KNOW YOUR MAC
- Hardware: the chip, CPU and GPU cores, unified memory and its measured speed.
- Active: the inference engines running and the models they have loaded, and when your Mac sits idle.
- Results: every benchmark, and Compare with other Macs on the public stats.
- Settings: the Tuner's score and recommendations, model makers, chat compression.
BENCHMARK
GPU memory bandwidth and compute, and real language-model speed (prompt and generation, in tokens per second), measured with MLX inside the app.
YOUR MAC ON YOUR IPHONE
Pair your iPhone with AiTuner: Monitor (Settings, Allow iPhone) to see your Mac live, at home or away, encrypted end to end.
PRIVATE BY DESIGN
Models and chats stay on your Mac: nothing you type is sent to an AI company. AiTuner is free; in return your benchmark results (never your chats) are shared anonymously to the public stats at aituner.app, as the license agreement you accept at first launch says.
Requires a Mac with Apple Silicon (M1 or later) and macOS 14 or later.
Ollama and LM Studio belong to their owners; AiTuner works with them and is not affiliated with them.
